A process for recovering iron as hematite from a base metal containing material involves performing a leaching step on the base metal containing material at atmospheric pressure in the absence of an oxidant, using a lixiviant to obtain a solid residue and a leachate containing dissolved iron therein. The lixiviant includes an acid and a chloride.
KEYWORDS hematite, recycling, pelletizing 1. Introduction The rolling is an essential industrial process for steel sheet production. During the deformations of steel, oxygen from the air reacts with the iron and forms iron oxides or scale as a fine layer on the surface of the steel strip. The constituents of mill
Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide Fe 2 O 3, that constitutes the most important iron ore because of its high iron content 70 percent and its abundance. Its name is derived from the Greek word for “blood,” in allusion to its red colour. Many of the various forms of hematite have separate names. The steelgray crystals and coarse ...

Surplus coke oven gases COGs and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work, lowtemperature hydrogen reduction of hematite ore fines was performed in a fixedbed reactor with a stirring apparatus, and a laboratory Davis magnetic ...
